# Complete Guessing Game with Non-Volatile Storage in Python

"Multi Stage Guessing Game and File Storage to store current level"
Create a three stage guessing game which stores current stage of user in hard disk, in each stage the user must guess the secret number in five attempts. Range of Secret number should be increased at stage like 1 to 10 in stage in 1, 1 to 20 in stage 2 and 1 to 30 in stage 3. If the user correctly guessed the secret number, the system should display "your guess is correct" and moves to next stage; otherwise, it should tell the user whether the guessed number is higher or lower than the secret number and proceed to the next attempt. If the user fails to guess correctly after five attempts, the game should end with the message "Game Over, You Lose the Game." If user successfully guessed in all the three stages, display "You won the Game with scored points", then points scored at each level and stops the game.

Note : If user lefts or stops the game after completing any stage, it should starts from next stage when user runs the program again.

At each stage the points will be awarded to user based on following condition

 Solved in points first attempt 100 second attempt 75 third attempt 50 fourth attempt 25 fifth attempt 10

Hint : Permanent  storage (File) is needed for this.
Objective : To learn the usage of Files

#### Program Explanation

Watch Previous levels for the guessing game logic, in addition

to store the level and points scored by user in hard disk we are using text file 'guess.txt.,

note:

split(':') split the string into list, colon (:) is the separator here

rstrip(',') removes comma(,) at the end of the string

open(), read(), seek(), write(), and close() are the file functions.

seek(0,0) moves the file pointer to beginning of the file.

open('guess.txt','a+') opens file in append mode (write without delete) and read mode.
